Re: #2 - Cobbler -- "No DHCP or proxyDHCP offers"

[Frank]

Hello Ron:

Good to see your name.
Thank you for the suggestion, but you 'lost' that one :)

So, yes, "pxe_just_once" was enabled.
Howewever ... still doesn't work after I had changed it, and done the 
Sync and restart. I also changed the boot order on the 
to-be-installed server, so that I had to choose PXE booting using the 
F-10 or F-12 key (not sure if that would make a difference). Not 
working. Furthermore, on another server, a server were cPanel had not 
been installed, Cobbler works just fine (with that pxe_just_once 
enabled setting).
Do you know where those records for servers were an install was 
performed get saved on the Cobbler server? I mean, maybe somehow the 
settings file update does not overwrite other settings as it then 
should, and I may try to 'delete' them manually. That, of course, is 
just a wild uneducated guess.


Best,
Frank
